According to the referee of the *Journal Origami Society of Japan*, maximizing the volume of a cup made from a square sheet of paper is a new problem proposed by the authors. Our previous research is presented in [2].

The origami wrapping problem, which has been studied by some mathematicians, looks for the biggest object that can be wrapped with a sheet of paper. See [1].
